Sib nqus particle imaging (MPI) yog ib qho tshiab imaging modality nrog lub peev xwm rau high-resolution imaging thaum tuav lub noninvasive xwm ntawm lwm yam tam sim no modalities xws li magnetic resonance imaging (MRI) thiab positron emission tomography (PET). Nws muaj peev xwm taug qab qhov chaw thiab qhov ntau ntawm cov superparamagnetic hlau oxide nanoparticles tshwj xeeb yam tsis tau taug qab cov teeb liab tom qab.

MPI siv qhov tshwj xeeb, qhov tseem ceeb ntawm cov nanoparticles: yuav ua li cas lawv hnov ​​​​mob nyob rau hauv lub xub ntiag ntawm magnetic teb, thiab tom qab tig tawm ntawm daim teb. Cov pab pawg tam sim no ntawm nanoparticles uas siv hauv MPI feem ntau yog muag rau MRI. Tshwj xeeb MPI tracers yog nyob rau hauv kev txhim kho los ntawm ntau pab pawg uas siv ib tug hlau-oxide core encompassed los ntawm ntau yam txheej. Cov tracers no yuav daws tau qhov teeb meem tam sim no los ntawm kev hloov qhov loj thiab cov khoom ntawm nanoparticles rau qhov yuav tsum tau ua los ntawm MPI.

Sib Nqus Particle Imaging siv lub cim geometry ntawm magnetics los tsim ib cheeb tsam dawb (FFR). Qhov taw tes rhiab ntawd tswj cov kev taw qhia ntawm nanoparticle. Qhov no txawv heev ntawm MRI physics qhov twg cov duab yog tsim los ntawm ib qho chaw sib xws.
